I am unable to post to the main forums and it has been more than 72 hours since I resubbed. I remembered that I had the same issue in the past and had to log out and then log back in. When I have tried that though, the website has been acting weird.
When I try to log out, it goes to a new page
https://us.forums.blizzard.com/en/wow/logout
and just sits there with the dots fading in and out. The web browser tab shows the page’s name as “Page Not Found”. When I hover over the account drop down, it shows the log in button. I click that and the page changes to
https://us.forums.blizzard.com/en/wow/logout
That just shows a 404 Not Found page with the “nginx” below that.
So, yeah, I cannot logout login to try and fix the posting issue as it is saying that none of the pages are found.
As one last note, one of the website updates a while ago required me to turn off my ad blocker off and I have never turned it back on. So, it is not even likely to be the cause.
EDIT: I forgot to mention, but I literally cannot logout right now. If I reload the page after to tries to go to the logout screen, I am still logged in. I cannot log out of the forums at the moment.
EDIT 2: I still cannot log out on my computer, but doing so on my phone seems to have allowed me to start posting on the forums. Something is definitely odd, but at least what made the page not found problem hit is not an issue right now.
